We've Completed the Historic Move to ERCOT

On Dec 9-11, 2023, LP&L finished connecting the remaining 30% of its system to the Electric Reliability Council of Texas (ERCOT). The completion of this historic move concludes over eight years of work and constitutes the largest migration of electrical load in state history.

LP&L diligently worked to plan the second and final migration of customers for several years and the result was a seamless migration of customers from one power grid to another. Over the weekend, affected customers were told to expect a one-time outage lasting no more than 30 minutes. The average outage time per customer over the three-day project was just under 10 minutes. During the first migration of customers to ERCOT over Memorial Day 2021, the average outage time per customer was 16 minutes.

Benefits of Joining ERCOT

Since the March 2018 approval of LP&L’s application to join the Electric Reliability Council of Texas (ERCOT), LP&L has been hard at work making infrastructure updates to connect with the ERCOT system. This type of interconnection is the first in Lubbock’s history and the first in the state in 25 years.

Joining the ERCOT system accomplishes the long-term goal LP&L set forth when we began this process over six years ago. It provides our customers a flexible and diverse portfolio of Texas power, meaning affordable and reliable electricity for many years to come.

LP&L customers can expect to see savings in power costs with the removal of expensive fixed capacity charges that aren’t required in ERCOT. Joining ERCOT also eliminates the need to build a new power plant at an estimated cost ranging from $350 million to $700 million.
